Metallurgical grade silicon is a purified form of silicon with a purity of around 98% or higher. Silicon is mostly found in the form of silica in the earth’s crust and this silica is then further reduced to metallurgical grade silicon. Metallurgical grade silicon is not highly pure due to the presence of impurities such as iron and aluminum. It has a wide application range in the semiconductor industry and is further purified for applications in the solar industry. Polysilicon, which is a key material in the manufacturing of solar cells, uses purified metallurgical grade silicon as a raw material. Polysilicon is also used in the manufacturing of various microelectronic devices. Electronic grade polysilicon is made from a purer form of metallurgical grade silicon than that used in the manufacture of solar grade polysilicon. A more purified form of metallurgical grade silicon is also known as upgraded metallurgical grade silicon. Metallurgical grade silicon is also used in the manufac...
